Quilter amplifiers

QUILTER LABORATORIES

In 1967 a musician friend complained that a good bass amp cost five times more than the $250 he had in his pocket. Pat Quilter a college student with a passion for audio electronics agreed to give it a try. Before long “Quilter Sound Things” were beginning to find a place in the musical landscape of Southern California. Soon amps were placed in several clubs on the emerging music scene of the Sunset Strip. Musicians raved about them. “They were the loudest amps around, and only one out of four blew which was more reliable than most.” said Quilter of those early days. But despite some close brushes with fame and fortune, the race went to better known brands. And so the young company refocused on the pro audio market.

THE QUILTER MISSION. 
Modern audio products are changing from conventional solid state to a much more efficient “switchmode technology” (often called Class D) that delivers more power with lower losses and lighter weight. The new technology is more complex and has stringent regulatory requirements, so it’s been developed first for large-scale 
applications such as cellphones, home theaters, car audio systems and large PA amplifiers. Meanwhile, the guitar industry is still stuck in the tube era. Pat Quilter, founder of QSC Audio Products and a veteran designer with over 45 years of experience, is one of the few designers whose career spans tubes, solid state, and the new switchmode technology. His mission is to combine a deep love of 
music, a deep understanding of tube behavior, and his expertise in switchmode design, to create new tools that will expand artistic possibilities, relieve performers of excess burdens, and exploit the latest mainstream technology to deliver higher quality and satisfaction at an affordable price.
